Development of a Composite Program Assessment Score (CPAS) for evaluation of a technology portfolio

Aviation is one of the safest modes of transportation, and statistics indicate the success of government and industry initiatives taken in this direction. However, the ever increasing air traffic and the relatively flat decline in the accident rate in recent history motivates efforts to continually enhance safety and security in aviation. The Aviation Safety Program office at the National Aeronautics and Space Administration has formulated a portfolio of technologies for improving safety in aviation. Five program-assessment metrics have been independently defined and quantified by different sources to objectively evaluate the effectiveness and the anticipated performance of these technologies. This paper addresses a framework to consolidate the five existing program-assessment metrics to develop a unified metric that simultaneously considers the relative importance of each.
